The activation of dioxygen by monovalent nickel complexes has proven to be a productive approach to the generation of new, metastable Ni-Ox species that include side-on and end-on superoxo and trans-μ-1,2-peroxo motifs. Recently, we have turned our attention to the heavier congener sulfur. Herein, we report the structural and spectroscopic characterization of a μ-η22-disulfido dinickel(II) complex, [(PhTttBu)Ni]2(μ-η22-S2), prepared by following either of two synthetic routes: (i) reaction of S8 with the nickel(I) complex [PhTttBu]Ni(CO) or (ii) the thermal decomposition of the nickel(II) complex [PhTttBu]Ni(SCPh3) via C-S bond cleavage.
